Figure 1. Anteroposterior (A) and lateral (B) chest X-ray:
Venous cannula (10 Fr Biomedicus, Medtronic®) inserted
in the jugular vein (a), arterial cannula (8 Fr Biomedicus,
Medtronic®) inserted in the carotid artery (b), right
thorax drainage catheter (c), pericardial drainage catheter (d), and
cannula tip (arrow). Even if in (A) and (B) the radiopaque portion of
the venous cannula suggests a correct position, the tip (arrow) of the
venous cannula is (unusually) above the radiopaque portion of the venous
cannula, thus suggesting a venous cannula kinking.
